is that the frog heart has You correctly answered: c. a single‚ fused ventricle. 05/ Review Sheet Results 1. Explain why the larger waves seen on the oscilloscope represent the ventricular contraction. Your answer: The ventricular contraction is of greater force than the atrial contraction since the ventricular contraction functions to send blood throughout the entire body (systemic circulation). The contraction of the atrium send blood only to the lungs and rest of the the heart (pulmonary

Body System Assignment Module 7: Cardiovascular System Case 1: A 76-year-old man of Eastern European heritage develops chest pain and is taken to the ED‚ where he is diagnosed with angina. During his assessment‚ the nurse hears carotid bruits. 1. Explain how the nurse would assess for carotid bruits? •When assessing the jugular venous pressure‚ you would palpate the carotid upstrokes and auscultate for carotid bruits (Bickley & Szilagyi‚ 2017). To assess for carotid bruits ask the patient

Treating Heart Failure When a patient’s heart is no longer able to pump a sufficient amount of blood around the body‚ they are referred to as having heart failure. The heart muscle has been damaged or overworked and is therefore unable to pump as effectively as before. Coronary heart disease is the most common cause of heart failure‚ cardiomyopathy and hypertension are also implicated (Peterson et al‚ 2002). Heart failure can present acutely or chronically. Chronic heart failure tends to worsen

Introduction Crash carts are very important in the medical field. They provide many advantages and little to no disadvantages when it comes to providing for the medical staff. Not only do they provide the necessary tools needed to take care of several different circulatory and respiratory complications but also have the necessary medications neatly organized for easy access. After concluding my research I found out a lot of interesting facts about not only the items that area inside the cart but

defect is bigger‚ symptoms are more pronounced. A larger volume of oxygenated blood in the left atrium flows back in the right atrium rather than being pumped out of the heart to the rest of the body. Treatment is often necessary. Ventricular Septal Defect A ventricular septal defect (VSD) is similar to an ASD. The difference is that the hole is located between the two ventricles (lower chambers of the heart). The effect is essentially the same. Oxygen-rich blood that would otherwise be pumped into

while the posterior aspect shows the left atrium. The atria form one unit and the ventricles another. The left ventricular free wall and the septum are much thicker than the right ventricular wall. This is logical since the left ventricle pumps blood to the systemic circulation‚ where the pressure is considerably higher than for the pulmonary circulation‚ which arises from right ventricular outflow. The heart has four valves. Between the right

Anticoagulants are considered more aggressive drugs than antiplatelets. They are recommended primarily for people with a high risk of stroke and people with atrial fibrillation. More than 2.7 million Americans have atrial fibrillation (AF)‚ an-arrhythmia of the heart where the atria (the heart’s pumping chambers) quiver instead of beat. As a result‚ not all of the blood is pumped out of the heart‚ allowing pools to collect in the heart chamber‚ where
